Error message

Chart not found

What it means

Raised as WarmUpCacheChartNotFoundError when the chart id passed to WarmUpCacheCommand does not resolve to a Slice row (db.session.query(Slice).filter_by(id=...).scalar() is None) and a Slice object was not supplied directly. Cache warm-up is aborted because there is no chart to warm.

Solutions

1. Verify the chart exists with GET /api/v1/chart/{id} before requesting warm-up.
2. Prune deleted chart ids from cache-warm-up schedules/config (CELERYBEAT_SCHEDULE or cache configuration).
3. Handle 404 per-chart in bulk warm-up loops and continue.

Example fix

# before
client.post('/api/v1/chart/warm_up_cache', json={'chart_id': 999})  # 404

# after
if client.get('/api/v1/chart/999').status_code == 200:
    client.post('/api/v1/chart/warm_up_cache', json={'chart_id': 999})

from superset.models.slice import Slice
from superset import db
if db.session.query(Slice).filter_by(id=chart_id).scalar() is None:
    raise ValueError(f'chart {chart_id} not found')

from superset.commands.chart.exceptions import WarmUpCacheChartNotFoundError
try:
    WarmUpCacheCommand(chart_id=chart_id).run()
except WarmUpCacheChartNotFoundError:
    prune_chart_from_warmup_schedule(chart_id)

When it happens

Trigger: POST /api/v1/chart/warm_up_cache with a deleted, nonexistent, or mistyped chart id; warming from a config list (e.g. cache-warm-up celery task settings) that references charts removed from the database.

Common situations: Scheduled cache warm-up jobs listing stale chart ids after cleanup; environment drift between config files and the metadata DB.
